DETACHABLE specificati@ of y Application and May 26,

To all 'whom itv may concern Be it known that I, HARRY'O. RUSS, a. citizen of the United States',and'resident of Swampscott, -in the county of Essex and State of ltlassachusetts,v have invented certain new and useful Improvements in -Detachable Wheel-Rims, of which thefcllowingis a specification. y

-This invention relates to vehicle wheels, and particularly to means for facilitating the mounting of the tires or rims, to enable the substitution of one rim or tire for another, relatively to the Afelly and spokes, to he readily effected. l

The principal object of the invention is to provide means whereby the'A weight and consequent momentum of the wheel itself may be utilized to facilita-te. the `mounting 'or def vmounting of the tireo'r rim of the Wheel..

To this and other ends the invention con` sists in improvements which I AVshall now proceed to describe and claim. A

which the section of.Fig..16 is mikem-Fig It), in fact., representing a section on line 16--16 of Fig. 18. Figs. 19 und 2O are views similar to Figs. 1 and 2 but illustrating anv other embodiment of the invention, for mounting anddemounting' a supplemental rim. Fig. 21. is an elevation, partly in' sec# tion, of the inner rim Amembers shown in TheA {ig-'ares oneach' of the three silieetsiof the drawingsxrelatevto a single embodiment offt-he invention.- Referring' lirst to' Figs.

l to 5 ii/uflusive and Figs. 8-and 'th-'the hubl 301,"- -polies 31, andv wood .folly 29 are, or may be," of any Well-known or pref-erred construct-ion. The -metal rim 39.,.having a llange at one edge, is preferably made slightly beveled. That is, it is nottruly cylindrical. vIn practice, the rim 32'is'shrunk on to the felly 29 and is customarily additionally seeureddiy. bolts','whicli latter are not shown'as thepresence or absence of such bolts has nothing to do with'myinvention. Fitting the rim 32 and retained in place by the flange is ring 34. having anannular `groove in its inner side face to receive one of the side ribs of an ordinary form of pneumatic tire 3G, the other side rib being engaged by the groove 37 of the removable ring 38. The portion of the rim ll'opposite the flange 33 is formed or provided with a plurality (two or more) of inclined ribs, cam ribs, or thread sections 39. For convenience of description l shall hereinafter refer to the portions 39 as threads,rsince they are interrupted so as to constitute va mutilated thread. The ring 38 is'formed or provided internally with interrupted threads 40 adapted to coact with the threads 39 of the rim 32 in a manner similar to a screw, the pitch of the threads, however,

being such that only a small portion of one be firmly gripped between the grooves 37 ind 35 of the rings 38 and 34 respectively. At a suitable point around the ring 38 I provide an abutment adapted. to be engaged by a strut 41 which in Figs. 1 and 8 is represented-as a screw-driver. The abutment is shown as a block 42 which is rigidly secured to theV side of the ring 38, said block being provided with two recesses so as to form twovshoulders 43 either one of which constitutes practically the abutmentI as hereinil'fter described, according yto which direction of rotation is given to the wheel in the act of mounting or demounting a tire. I do not limit myself to ,this particular method of providing the abutment or abutments, it being only essential that the ring 38 shall have some portion against which one end ofa strut may be placed to enable the other endy of such strut to contact with the ground.

In operation, when the tire has been fitted to place against the ring 34, the ring 38 is then placed against the other side of the tire and said ring 38 is turned so that its internal threads 40 will enter between the ends of the externalthreads 39'of the rim 32 and then thee-said ring 38 is turned as far as may be convenient. Tt is to b'nderstood,

of course, that the wheel jackedmlup from the ground. The strut 41 is thgh placed with one end engaging one of the zibutments 43, and the wheel is given a sharp whirl to the left, the strut being kept in its position somewhat tangential to the tire, the result of the turn given to the wheel being that the lower end of the strut is carried into contact with the ground and stopped. Themornentum of the Wheel, due to its weight, causes `the wheel and its rim 32 to continue'moving sufficiently so that often a single operation of this kind will be suicient to cause the ring l38 to bind the tire tightly. Any suitable means may be Aprovided for retaining the ring 38 in its firmlyset position. Said means may consist, as shown in Fig. 5, of a pin 44, projecting through a portion of the rim 32, and adapted to engage a suitable locking recess in the inner surface of the ring 38, said pin being carried by a spring 45 (seefilso Fig. 1) pivotally connected at 46 to the inner wall of the rim 32 so that the spring, carrying its pin 44, may be lifted an swung aside to hold the pin 44 away fr ol the hole or aperture through which'it projects when in operative position.'l In Fig. 1 the dotted line position of the spring indicates its position when swung outwaidly, as just described. To "prevent the passage of mud or water through the Vspace between the ends of the threadsgl may employ a gate 47 pivotally supp'orted at 48', as shown in Fig. 9, in a recess of one'ofthe members, and havingia spring'49 whereby the gate will automatiallysnapinto the po.-

sition shown by full lines in 9, so that its end will engage the end of the thread of overlap, in which case, some portions of the ring 38V would, in cross section, show two threads 40, as indicated in Fig.I 7.

In Fig. 6 Irepresent a rearrangement of the two rings 34, 38, to adapt the same for use in connection with a Dunlop tire, the two rings being then simply applied to their grooves facing-outwardly, or apart from each other, instead of toward each other, as shown in Figs. A5 and 7. As shown in said Fig. 6, the block 42 would then be applied to the sideof `the ring 38, which is then outermost. To remove the ring 38 and the tire, assuming the tire to be deflated and the wheel jacked up, the lock device 44, or 47, or both of them, are released, and then the screw-driver tool or strut 41 is placed in engagement with the abutment presented by the block 42, and the wheel is whirled sharply to the right until the strut comes in contact with the ground, thus the momentum of the wheel provides the force to cause the ring vto unscrew, so that it can be re- 4 moved. The tire is then drawn away from the rim 32, the bevel of the rim rendering such removal comparatively easy. ,Y

Referring to Figs. 10 to 18, inelusive, the portions bearing the same reference characters as the figures hereinbeforedescribed,

carries Aan inner folly-.band or fixed I'iin 50,- having a'beveled Hangs 51, around one edge, and at the other edge having an inwardly' extending annular shoulder 52, the latter having a ring-shaped inner flange 53. The' flange '53 is fprmed with threads 54. The outer or demountable rim 55 has a.

lange and threads 39, to coact with rings' 34 and""38,'fin the manner hereinbeore .de-

scribed :infconnection with 1 and'.

Said'rim 55 is 'provided with an internally beveled seat 56. to bear lupon the beveled Harige 510i the felly band'. A ring- 57 (Figs. 13, 14 and 15) is interposed betmen the'fel'ly band 50 and rim 55, said. ringf having on its outer'surface a. "series"o'ftcaxpifacedlugs 58 to engagethe beveled {gametithe rim 55, as 'clearly fshownlin.

threads 59 (Fig. 14) to engage the threads 54 of the telly band 50. A stop screw GG (Fig. 17) is employed For a purpose here inafter described. A locking bolt (il is adapted to be. passed through the wood telly 29, and 'the annular shoulder of the :telly band 50 Assuming the tire to be in place on the rim 55, between the rings 34, 38, and the Wheel jacked up from the ground, the intermediate ring 57 is inserted to the p0` sition shown in F ig. 15, and turned sufficiently to cause its threads 59 to commencel to engage the threads .34. The rim having the tire is then applied to the wheel and a strut 4l such as hereinbeforc described is then applied to the proper abutment shoulder 43 of the block 4'2. and the Wheel and tire revolved in the saine manner as hereinbe fore described, the Contact of the strut with the ground causing the momentum of the Wheel and tire to set the demountable rim tightly in place. Then the locking bolt tii is put in place and tightened up. To demount or remove the rim 35 and its tire. which latter is indicated by dotted lines in Fig. 10. the bolt C1 is loosened and the strut is ap`v plied to the other abutment shoulder 43. and the wheel whirled to thc right so as to loosen the ring 57 to enable the demountahle rim and the tire to be removed. In Figs. 19 to 26 inclusive I illustrate another embodiment of the invention, operating on the same principle', for mounting and demount` ing an assembled rim and tire. ln this con,` struction there is a fixed rim or telly band 50 having a beveled flange 51. and an outer rim 55 'which is demountable, these parts being substantially the same as those illustrated, in Figs. 10 and 1l, rings 34 and 38 similar to those in Figs. l. 2, 10 and 11 being employed for holding the tire (indicated by dotted lines in Fig. 19) on the demountable 'tire rim 55. The felly band 50 is formed or provided with lugs 69. said lugs having cam-faced ribs or threads tif.. The outer demountable rim 55 is formed with internal cam ribs or threads (i4 (Figs. Q2. Q3 and Q5). The felly band 50 is provided with a slot (i5 (Fig. 21), and the Wood fellv 29 is provided with a slot 66, (Fig. 20). these tivo slots being provided for the passage of the stem of the tire-inflating valve. said stem passing. through a hole (i7 in the rim 55 (Fig. 2Q). No slot is needed in the rim 55. because there is no rotative movel ment of the rim 55 and the tire relative to each other. The slots 65. (iti are provided so as to permit the rotative movement ot' the outer rim 55. and the tire and its valve. stem. relatively to the fellv band 50 and the Wood folly 29. A bolt 68 (Figs. Q4 and Q5) is adapted to be passed through the wood felly 99, one end of said bolt passing through a slot 71 in a lug 70 projecting from a Wedge-block 69 (Fig. 26). l do not limit member myself to the exact shape of wedge illustrated in Fig. 26.

The bolt and the ylocking-block (if) are employed to lock the demountable rim firmly in place against an unscreiving motion. and it may also have the effect of drawing the demountable rim more tightly into place. As suming an inflated tire being connected to the demountable rim 55, and the wheel jacked up. and tbe valve stem passing through the slots (i5, 66. the rim 55 and its tire is slipped on to the telly band 50 and the threads (it. partially engaged with the threads 33 by a rotative movement. A strut such as that indicated at 41 in Figs. 1 and S. is then placed in contact with the proper abutment of the block l2. and the wheel whirled or turned in the manner hereinbetore described. so as to cause the tiriu setting of the demountable rim and its tire. Then the locking bolt (3B is applied. To demount or remove the rim 53 and the tire. the strut is applied to the other abutment and the wheel turned in the other direction in the manner hereinbeiore described. the bolt 69 having, ot' course, first been loosened.

As best .shovvn in Fig. S, each of the tivo abut-nient shoulders -l-'i has. opposite the face which is to be engaged b v the strut 4l, a guard which prevents accidental contact of the abutment shoulder with anything which might tend to either break away the abutA ment or dislodge the member which carries the abutment. Such guard is indicated at 43a. having an inclined portion 43". `When wheels including my invention are in use on an automobile. running close to a. curb stone can produce no ill results because any close Contact with curbing would only result in said curbing engaging one or the other of the inclined surfaces 43". so that the abutment shoulder 49. cannot contact with the curbing. ',lherefore l have provided against accidental damage to the abutment member, and also provided against liability of the automobile mounting the curbing by reason of Contact of the abutment member with such curbing.

ln each of the above described embodiMv ments of my invention they part bearing thc` oppositelvv tai-ing abutments I.lil constitutes the demountable member of the peripheral portion of the Wheel. and the other parts of the said peripheral portion which turn in unison when the demountable member is ar rested by the strut collectively constitute the body member of the peripheral portion ot' the wheel. said body member being practically a part oi the main structure. which includes the felly, spokes and hul Because of the fact that the abutments face in opposite directions, the rotation of the body member in one direction attaches the demountable and causes it to secure the tire,

while the rotation of the body member in the opposite direction releases the demountable member and causes it to release the tire, the torque or turning moment of the jacked-up wheel being therefore utilized for both purposes. The guards 43 are oppositely acting guards in the sense that one acts as an abutment protector when the wheel is rotating for` ard, while the other acts as an abutment protector when the wheel is rotating backward. l

I. claim:

1. A wheel having a peripheral portion comprising a body member and a demountable member, said members being provided with inter-engaging threads, the demount` able member having oppositely facing abutments each adapted to be enga ed with one end of a strut the other end o which contacts with theground to hold the deinountable member while the body member turns relatively thereto, one abutment being formed to engage the strut when the bodyl member is turning forward, While the other abutment is formed to engage the strut when the body member is turning backward, whereby the torque of the body member and the wheel parts moving therewith may be utilized bothfte attach and release the demountable member.

2. A wheel having a peripheral portion comprising two members rovided with interengaging threads, one o said members cess being .of a height to serve as a guard opposite the side which is engaged with said strut.

In testimony whereof I have aflixed my signature, in presence of twoy witnesses.
